Exercise 1: Zero-Trust Application

Objective

Apply concepts from Zero-Trust to solve a real-world architecture problem.

Scenario

You are an AI Infrastructure Architect at a [company type]. The organization needs [specific requirement related to module topic].

Context:

  • Current infrastructure: [description]
  • Pain points: [list of issues]
  • Goals: [list of objectives]
  • Constraints: [budget, timeline, resources]

Tasks

Task 1: Analysis (30 minutes)

Analyze the current state and identify:

  1. Key challenges and bottlenecks
  2. Architectural gaps
  3. Risk factors
  4. Opportunities for improvement

Deliverable: Written analysis (1-2 pages)

Task 2: Architecture Design (60 minutes)

Design an architecture solution that addresses the challenges:

  1. High-level architecture:

    • Create component diagram
    • Define responsibilities of each component
    • Show interactions and data flows

  2. Key decisions:

    • Technology selections with rationale
    • Design patterns applied
    • Trade-offs considered

  3. Non-functional requirements:

    • Performance targets
    • Security measures
    • Cost estimates
    • Scalability approach

Deliverable: Architecture diagrams and design document (2-3 pages)

Task 3: Implementation Plan (30 minutes)

Create an implementation roadmap:

  1. Phases: Break work into phases (3-5)
  2. Timeline: Estimated duration for each phase
  3. Dependencies: What must happen first
  4. Risks: Potential risks and mitigation strategies
  5. Success metrics: How to measure success

Deliverable: Implementation plan (1 page)

Task 4: Stakeholder Communication (30 minutes)

Prepare a stakeholder presentation:

  1. Executive summary: Key points in 1-2 slides
  2. Architecture overview: Visual representation
  3. Business value: Benefits and ROI
  4. Timeline and costs: High-level estimates
  5. Risks and mitigation: What could go wrong

Deliverable: Slide deck (5-7 slides)

Evaluation Criteria

Your solution will be evaluated on:

  • Architecture quality (40%): Soundness of design, appropriate patterns
  • Documentation (30%): Clarity, completeness, visual communication
  • Strategic thinking (20%): Business alignment, long-term vision
  • Communication (10%): Stakeholder-appropriate presentation

Solution Approach

Hints

  1. Start by clearly defining requirements
  2. Consider multiple architecture alternatives
  3. Document your design decisions (ADRs)
  4. Think about operational concerns (monitoring, maintenance)
  5. Validate assumptions with research

Common Mistakes to Avoid

  • ❌ Over-engineering the solution
  • ❌ Ignoring cost considerations
  • ❌ Not addressing security and compliance
  • ❌ Poor communication of trade-offs
  • ❌ Lack of implementation roadmap

Time Estimate

Total: 2.5 hours

  • Analysis: 30 minutes
  • Design: 60 minutes
  • Planning: 30 minutes
  • Communication: 30 minutes

Submission

  1. Create a directory: solutions/exercise-1/
  2. Include all deliverables:
    • analysis.md: Analysis document
    • architecture.md: Architecture design
    • implementation-plan.md: Implementation roadmap
    • presentation.pdf: Stakeholder slides
    • diagrams/: Architecture diagrams

Additional Resources

  • Refer to lecture notes for patterns and practices
  • See resources.md for tools and references
  • Review case studies for inspiration
